Various government agencies are interested in terrestrial vegetation since the information contributes to the fulfillment of their goals. The USDA's Forestry Service analyzes land cover to assess the potential for fire. The Environmental Protection Agency is concerned about the environmental impact of hazardous substances particularly on watersheds and may use vegetation as an indicator of harm. The Department of Interior also tracks vegetation, particularly in the national parks.
